FAQs on Orbital & Escape Velocity - 1 Video Lecture - Physics for JEE Main & Advanced

1. What is the definition of orbital velocity?

Ans. Orbital velocity is the minimum velocity required for an object to maintain a stable orbit around a celestial body, such as a planet or a moon. It is the speed at which the centripetal force due to gravity is balanced by the object's inertia.

2. How is escape velocity different from orbital velocity?

Ans. Escape velocity is the minimum velocity required for an object to completely escape the gravitational pull of a celestial body. It is greater than the orbital velocity because it needs to overcome the gravitational attraction and reach an infinite distance from the body.

3. How is orbital velocity calculated?

Ans. The orbital velocity of an object can be calculated using the formula: V = sqrt(G * M / R), where V is the orbital velocity, G is the gravitational constant, M is the mass of the celestial body, and R is the distance from the center of the body to the object.

4. Can an object have multiple orbital velocities?

Ans. No, an object can have only one orbital velocity for a specific distance from a celestial body. The orbital velocity depends on the mass of the celestial body and the distance from its center. Changing either of these parameters will result in a different orbital velocity.

5. What factors affect the escape velocity of a celestial body?

Ans. The escape velocity of a celestial body is determined by its mass and radius. A larger mass or a smaller radius will result in a higher escape velocity. The escape velocity is independent of the mass or size of the escaping object.
